Simple lorentz trans. question

I have been trying to derive the equation for relative velocity for a while and have had no success. I don't know, perhaps I am slightly misunderstanding SR or something. Does anyone have suggestions for understanding the derivation?

You mean, derive it from the Lorentz transformation? Just take an object with velocity v in one frame, find the coordinates of two events on its worldline (to make it simple the first could be the origin, the second could be the event x=vT, t=T), then find the coordinates of the same two events in another frame moving along the same axis of the first frame's coordinate system, and find (change in position)/(change in time) for the events in the second frame.

If you intend to derive it without using the Lorentz transformation have a look at
W.N. Mathews Jr. "Relativistic velocity and accelereation transformation from thought experiments," Am.J.Phys. 73 45 (2005)
I will send you a simpler approach to the same problem
